KWMR and the West Marin Disaster Council Have New Emergency Capabilities  At a ceremony at the Point Reyes Station Firehouse yesterday, Richard Dillman, KWMR's Transmitter Wrangler, accepted a donation of the communications van from Greenpeace.  Dillman, Disaster Council Coordinator Libby Colman and KWMR Board Chair David Bunnett comment on the van's ability to keep the station on the air and to provide emergency communications during disasters, as George Clyde reports.  (The van will be at the Marconi Boat Launch in Marshall from 11 AM to 3 PM Saturday for the Marshall Disaster Preparedness Fair.)
